Asynapsis in Lolium perenne

Chromosoma, 1978
Eighteen plants displaying varying degrees of asynapsis ranging from weak to very strong were found among four out of six populations of Lolium perenne L. (2n=14) which had been subjected to three cycles of directional phenotypic selection for productivity of green material.

Anther Culture of Lolium Perenne and Lolium Multiflorum [PDF]

open access: possible, 1990
Albino as well as green plantlets were obtained by anther culture of Lolium perenne L. and L.multiflorum L. Isozyme and flow cytometric analyses showed the microspore origin of these plantlets. There is a clear genotype effect on anther culture response and on the ratio of green to albino regenerants. The majority of regenerated plantlets were albinos,

The typification of Lolium perenne L. and Lolium temulentum L. (Poaceae)

Botanical Journal of the Linnean Society, 1992
LOOS, B. P. & JARVIS, C. E., 1992. The typification of Lolium perenne and Lolium temulentum (Poaceae). The typification of the Linnaean species Lolium perenne and Lolium temulentum has been studied. Lolium perenne is typified by material in LINN, as proposed by Terrell, but it has been necessary to select a lectotype for L.

Cytomixis in Lolium perenne

Chromosoma, 1976
Cytomixis is a spontaneous process occurring through the formation of cytoplasmic bridges between adjacent pollen mother cells. This phenomenon was observed in the pollen mother cells of 3 genotypes of Lolium perenne which had been subjected to directional selection for productivity of green material.

A possible virus disease in Lolium perenne

Euphytica, 1956
Two types of abnormal plants have been observed in clonal plantations of perennial ryegrass. Plants of the first group were characterized in early spring by a dense dwarfed growth of distorted blue-green leaves. Those of the second group became recognizable later in the season, because of their somewhat stunted growth and the yellow, orange or pale-red
